Summary Outcrossing rates in natural populations of Lupinus nanus Dougl. have been found to vary from nearly zero to nearly 100 percent (Harding and Horovitz, 1969; Harding, 1970). These studies were based primarily on a group of northern populations of subspecies apricus (Elliott, Harding, and Mankinen; paper VI). The purposes of this paper are (1) to report estimates of outcrossing for the other subspecies of L. nanus , (2) to report estimates of outcrossing for the closely related species, L. bicolor, L. affinis, L. polycarpus , and L. pachylobus , (3) to discuss the relationship between these estimates of outcrossing and autofertility, and (4) to discuss the relationship between outcrossing and phenotypic and genotypic variability maintained in populations.
